PIR Sensor HC-SR501

PIR Sensor HC-SR501 – Motion Detection Made Easy for Your Projects

The PIR Sensor HC-SR501 is a versatile and easy-to-use passive infrared (PIR) sensor designed for detecting motion in your home automation, security, or IoT projects. It’s perfect for creating systems that require motion detection, such as security alarms, automated lighting, robotics, and other sensing applications.

The HC-SR501 uses infrared technology to detect changes in infrared radiation caused by motion, typically from a human body or animal. Once motion is detected, the sensor sends a high signal to trigger an output device, such as a light, relay, or alarm system. The sensor is highly adjustable, with built-in sensitivity and delay time settings, allowing you to fine-tune it according to your project’s needs.

With its low power consumption and simple interface, the PIR Sensor HC-SR501 can easily be integrated into Arduino and Raspberry Pi projects. Whether you want to automate your lighting system, build a motion-activated alarm, or design an intelligent robot with motion detection capabilities, this sensor is the perfect addition to your project.

Key Features:

• Passive Infrared (PIR) technology for detecting motion
• Adjustable sensitivity to detect movement from various distances
• Delay time setting to adjust the duration of motion detection
• Low power consumption, making it ideal for battery-operated applications
• Easy interface for integration with Arduino, Raspberry Pi, and other microcontrollers
